Kosterlitz-Thouless transition of the quasi two-dimensional trapped Bose gas
Markus Holzmann, Werner Krauth
We present Quantum Monte Carlo calculations with up to N=576000 interacting bosons in a quasi two-dimensional trap geometry closely related to recent experiments with atomic gases.…
Renormalization group approach to exact sampling
Cedric Chanal, Werner Krauth
In this Letter, we use a general renormalization-group algorithm to implement Propp and Wilson's "coupling from the past" approach to complex physical systems. Our algorithm follow…
Off-diagonal long-range order, cycle probabilities, and condensate fraction in the ideal Bose gas
Maguelonne Chevallier, Werner Krauth
We discuss the relationship between the cycle probabilities in the path-integral representation of the ideal Bose gas, off-diagonal long-range order, and Bose--Einstein condensatio…
Cluster Monte Carlo algorithms
Werner Krauth
In recent years, a better understanding of the Monte Carlo method has provided us with many new techniques in different areas of statistical physics. Of particular interest are so…
Liquid, Glass and Crystal in Two-dimensional Hard disks
Ludger Santen, Werner Krauth
We study the thermodynamic and dynamic phase transitions in two-dimensional polydisperse hard disks using Monte Carlo methods. A conventional local Monte Carlo algorithm allows us…
Comment on ``Critical temperature of trapped hard-sphere Bose gases''
Werner Krauth
In this comment, I discuss a recent path-integral Monte Carlo calculation by Pearson, Pang, and Chen (Phys. Rev. A 58, 4796 (1998)). For bosons with a small hard-core interaction i…
